W'ASHING AND DYETNG PJTACHINE.

Application filed April 9, 1912.

T 0 all whom it may concern:

Be it known that T, JAC UES Sorrnmarr, a citizen of the Swiss Confederation, residing at Brugg, Switzerland, have invented a new and useful Yarn l/Fashing and Dyeing Itlachine, of which the following is a specification.

My invention relates to machines for dye ing or bleaching hanks of yarn.

it provides a machine of this character which automatically performs the operation of shifting the hanks of yarn so that the dye or bleach acts on every portion, thereby pro ducing a hank of uniform shade throughout.

Tn dyeing or bleaching yarn in hanks, the hanks are pushed onto sticks or staves and these latter are so laid transversely over the dyeing trough that the hanks dip partially into the dye. in order to dye the hanks uniformly throughout, the position of the hanks upon the sticks is changed from time to time so that at each time such change of position takes place, that part of the hank which is situated above the surface of the dye is dipped into the dye.

The present invention provides improvements in machines which have been used to perform automatically the above mentioned operation of shifting the hanks of yarn.

The approved operation of the machine is attained by using a hank carrier consisting of two bars rigidly fixed with respect to one another and by rotating the carrier alternately about the two bars in such a manner that the upper bar always turns around the lower one. The hanks of yarn follow the descending bar because of its weight without stretching the threads in any particularly dangerous manner.

Tn the accompanying drawing forming part of this specification, like numerals of reference indicate like parts and Figure 1 is a sectional elevation view taken on line lt-B of Fig. 2, through a machine constructed according to my invention showing in dotted lines the dye vat disposed beneath the machine. Fig. 2 is an end section view taken on the line CD of Fig. 1 and showing the dye vat with the hanks of yarn descended therein. Figs. 3, 4, 5, and 6 illustrate the successive stages in which the yarn supports are handled, and the relation of the specification of Letters Patent.

yarn support to the parts cooperating therewith.

Referring to the drawings, the rails 1 and 2 are suitably arranged over the fixed vat k and the machine is so constructed, as will he hereinafter set forth, as to travel along the rails 1 and 2 above the vat.

The machine proper comprises a casing or frame 0 having mounted on each side thereof rollers a and 0; adapted to travel on therails 1 and 2 and support the machine over the vat it. As shown in Fig. 2 within the cats ing is mounted an electric motor 3 adapted to drive the machine and shifting mechanism comprising a part thereof, through a series of intermediate gearing driving the gears d and a rotatably mounted on the pivots 6 and 6, respectively, carried at each side of the lower part of the casing of frame 0 and disposed one on each side of the vat 7c. The gears 4c and a each carry a ring 7 and 7, respectively, and each is rovided with live teeth 8 and 8, the rings and 7 being fastened thereto by means of screws. Gears 9 and 9 are fixed to the pivots 6 and 6, re spectively, preferably by means of keys and mesh with the gears 10 10' rotatably mounted on pivots in the wheels 4,4 and each connected with a disk 11, 11 carrying a crank pin 12 and 12, respectively. The diameter of the pitched circle of each of the gears 10 and 10' is preferably, one-fifth of that of the gears 9 and 9. Each of the crank pins 12 and 12 projects into a slot 13 and 13 of the wheels and 15, said last mentioned wheels being each provided with five sockets 1d and 14: on the periphery thereof and the wheels 15 and 15 are rotatably mounted on the disks 16 and 16', respectively which in turn, are secured to the bars 17 and 17 which are adapted to be horizontally dislaced in the direction in which the machine is traveling by means of the two pairs of lovers 18 and 18 (Fig. 1). The two pairs of levers 18 and 18 are pivotally mounted at both sides of the machine, one lever of each pair being connected, by means of a rod 105, with a regulating device for'varying the traveling direction of the machine.

Each of the rings 7 and 7 works with the corresponding wheels 15 and 15, respectively, together with two pairs of hooks the rings 7 and 7 are lifted away from the notches by the teeth 8 and 8 of the rings 7 so that the lower bar f of the support 6 1s raised above the level of the liquid, the

lower bar is then seized and lifted up by a pair of hooks 20 (or 21 traveling in the opposite direction). Referring particularly to Figs. 3 to 6 inclusive, it will be seen that the upper bar 6 together with the hanks m are then allowed to fall down, the bar 6 coming to rest on the rings 7 and 7. In order to bring the bar 6 in front of the sockets 14 and 14 of the wheels 15 and 15" so that it can be seized thereby and pushed along by the tappets for a second tipping around the bar 6 in the same rotary di rection as in the first case, the wheels 15 and 15' are rotated for a short period of their revolution in a reverse direction with respect to the rings 7 and 7 by means of the crank pins 12 and 12 and are then again pushed forward in the rotary direction of the rings 7 and 7 The wheels 15 and 15 are consequently moved in circles with respect to the rings 7 and 7. They do not, however, perform a uniform movement but an intermittent partly oppositely directed movement. When the wheels 15 and 15 rotate in the same direction as the rings 7 and 7 their speed, which is regulated by the rotating crank pins on the rotating rings 7 and 7, is greater than that of the rings and it is during this period that the bar 0 is seized by the tappets of the wheels 15 and 15 and pushed forward after the support 6 has turned for the first time through 180, and at the same time the hooks 20 will release the bar f so that the support 5 turns a second time through an angle of 180. The wheels 7 and 7 then let the support Z) down onto the rails 22 and 22 which are fastened to the pair of levers 18, 18. The sockets 14, 14 of the wheels 15, 15 push the supports 5 in the direction of travel of the machine so that they slide from the rails 22, 22 and come to rest in the notches in the vat h. The hooks 20 and 21 are looselymounted on two parallel shafts and 26 mounted in the side of the machine and each of which is connected by means of a spring with an arm attached to the shaft 25 and 26 so that if the hooks encounter a fixed object, a breaking of the hooks is avoided.

Each of the shafts 25 and 26 is driven from a shaft 29 by means of a connecting rod 28 and 28 and cranks 27 and 27. The

shaft 29 is connected by gears with the electric motor 3 which drives the shaft. In order that the one or the other or even both of the shafts 25 and 26 may be thrown out of working engagement at releasable coupling, not shown in the drawings, is provided for each of these shafts, 25 and 26, by means of which the shaft 25 or 26 can be connected to the actuating connecting rod.

The pairs of hooks 20 and 21 are worked according to the direction in which the machine is traveling, but both pairs of hooks may be placed in the inoperative position so that the machine only lifts the supports b and sets them down again on the vatwithout occasioning any rotation of the supports or change of the hanks.

If one of the shafts 25, 26 is coupled to the electro-motor 3 or is disengaged therefrom, the traveling direction of the machine is changed and this is effected by means of a lever (Fig. 1) which is secured to a shaft 68. .By means of this lever 95, a coupling, not shown in the drawing, is operated so that the direction of rotation of the shaft 106 will be changed. This shaft carries cog wheels 107 which mesh with racks fastened to the rails 1 and 2. Therefore, by varying the direction of r0- tation of the shaft 106, the traveling direction of the machine is varied.

The shaft 68 is locked in its position by means of the lever 98 engaging the notches of a sector secured to said shaft, and said lever 98 is held in said notches by a spring (Fig. 1) so that any unintentional displacement is prevented and the shaft 68 can only be rotated if a special effort is made to this effect. In a similar manner, a shaft 50 rotatably mounted in the frame a is prevented from rotating by a spring controlled pawl loosely mounted on shaft 68 so that an accidental rotation of the shaft 50 controlling the coupling and uncoupling of the hook shafts 25, 26 from the driving rods 28, 28 is avoided.

A shaft 57 is pivotally secured in the machine frame at the side of the shaft 68 and can be turned by a spring 102 which engages an arm 101, said arm being adapted to actuate a switch lever by means of a rod not shown in the drawings, whereby a resistance is connected up in series to the motor.

In order to start the machine the shaft 120 is rotated by means of a hand wheel so that the circuit over the electro-motor is closed.
